Abstract: 652,449. Stencilling. COURTNEY, J. July 6, 1948, No. 18129. Convention date, July 24, 1947. [Class 100 (ii)] In printing by means of a stencil on textile fabric, a traversing pressure is applied to a colour-impregnated absorbent layer (e.g. felt) superimposed on the screen. One or more rollers may be used to apply the pressure. Fig. 5 shows two rollers 12 carried by a carriage comprising brackets 13 and rods 16 extending over a number of stencils spaced longitudinally of the intermittently moving fabric, separate pairs of rollers being provided for each stencil ; the carriage runs on wheels 14 on fixed transverse guide rails 17 and is reciprocated by chains passing over lateral sprockets ; the roller spindles are fixed to plates 22 slidable in guides 26 on mounting plates 35, their spring loading 31 being adjustable by means of hollow screws 28 surrounding adjustable stop screws 29. The felt may be mounted on a frame detachably fitted within each stencil frame ; the fabric may be freed for feeding (a) by raising the stencil frame or frames, in which case metal strips may be attached to the underside thereof laterally of the fabric to raise the pressure rollers ; or (b) by lowering the feed table, in which case the stencil frames may extend over fixed marginal portions of the table which support the pressure rollers during feeding of the fabric. Fig. 3 shows an inking device mounted above a single pressure roller; ink supplied through a flexible conduit to pipes 38, parallel to the roller spindle 20 and secured to the mounting plates 24 by brackets 37, is sprayed through outlets 39 on to the felt layer.
